Findings from a new mouse study indicate that elenolic acid, a natural compound found in olives, can significantly lower blood sugar levels and promote weight loss. This research suggests the potential for developing safe, inexpensive natural products for managing obesity and type 2 diabetes. Obese diabetic mice treated with elenolic acid showed improved blood sugar regulation and weight loss comparable to, or better than, current diabetic medications. The study highlights the compound’s ability to induce metabolic hormone release in the gut, promoting satiety and reducing food intake. Researchers are now investigating the compound’s absorption, distribution, metabolism, and excretion to ensure its safety for future clinical trials.

Mice treated with the natural compound experienced weight loss and enhanced blood sugar regulation. New research from a mouse study indicates that elenolic acid, a compound naturally occurring in olives, may reduce blood sugar levels and promote weight loss. This study could lead to the creation of affordable and safe natural products designed to help manage obesity and type 2 diabetes in humans.
The researchers found that after just one week, obese mice with diabetes that were given oral elenolic acid weighed significantly less and showed better blood sugar (glucose) regulation than before treatment and compared to control obese mice not receiving elenolic acid. The glucose-lowering effect was comparable with that of the injectable diabetic medication liraglutide and better than metformin, one of the most common oral medicines for type 2 diabetes.
“Lifestyle modifications and public health measures have had limited impact on the rising prevalence of obesity, one of the top risk factors for type 2 diabetes,” said research team leader Dongmin Liu, PhD, a professor in the Department of Human Nutrition, Foods and Exercise at Virginia Tech. “Available obesity drugs are ineffective in weight loss maintenance, expensive, and/or carry potential long-term safety risks. Our goal was to develop safer, cheaper, and more convenient multi-targeting agents that can prevent the occurrence of metabolic disorders and type 2 diabetes.”
Hana Alkhalidy, PhD, a research scientist in Liu’s lab at Virginia Tech, presented the findings at NUTRITION 2024, the flagship annual meeting of the American Society for Nutrition held June 29–July 2 in Chicago.
Focus on Bioactive Compounds
Liu’s research team focuses on discovering bioactive compounds from natural products for diabetes management. Previously, they looked for specific molecular targets for natural compounds in parts of the body that actively help regulate metabolism, such as the pancreas, muscle, fat tissues, and liver. However, since natural products typically have poor bioavailability, they decided to see if they could instead target metabolic hormone secretion in the gut to indirectly regulate metabolic function.
For the new work, the researchers began by identifying natural compounds that act on L-cells, which contain two metabolic hormones released during a meal. These hormones, called GLP-1 and PYY, work together to promote satiety and prevent overeating while also controlling blood sugar levels and metabolism. The screening process revealed that elenolic acid, which is found in mature olives and extra virgin olive oil, can induce the release of these hormones in the gut. They were able to make elenolic acid by breaking down its precursor oleuropein, which is less expensive than extracting it directly from olives.
Promising Results in Mice
Tests of the compound in obese mice with diabetes revealed that mice that received oral elenolic acid experienced significant improvements in their metabolic health compared to obese control mice. After four to five weeks of treatment, the mice showed a 10.7% reduction in obesity as well as blood sugar levels and insulin sensitivity that were comparable to those of healthy lean mice.
The elenolic acid also significantly reduced food intake and promoted weight loss, which are associated with improved circulating levels of PYY and GLP-1 and the downregulation of agouti-related peptide in the hypothalamus. Agouti-related peptide is known to increase eating and weight gain when overexpressed.
“Overall, the study showed that elenolic acid from olives has promising effects on hormone release and metabolic health, particularly in obese and diabetic conditions,” said Liu. “The compound seems to mimic the physiological conditions of eating to directly promote gut metabolic hormone secretion, which helps regulate energy balance and metabolic health.”
According to the researchers, the concentration of elenolic acid in olive oil or olives is very low, so the benefits seen in this study would most likely not be gained from olive products alone.
The research team is now working to understand how this compound creates metabolic benefits by analyzing its journey through the body to find out how it is absorbed, distributed, metabolized, and excreted. This will also reveal insights into its safety for future clinical trials.

Great!
Now maybe they will get those horrible commercials off TV with fat people sing about their damn A1C!...................
Brought to you by the olive growers association
Yup. Those are real channel changers for sure.
Green olives or black olives and how many per day?...
... This is good news in my opinion
Olives ruin my appetite, so this might work!
I pick all the olives off my pizza slices.
(Usually ordered by a friend or neighbor).
I scanned for type of olive to no avail. I’ve heard that kalamata olives are healthiest.
bump for later
So far I have noticed three: A Hispanic-looking woman, a middle-aged white woman and a black man.........but no white MEN. So, they are basically saying we don’t want white men to buy our products..................
How about a teaspoon of olive oil?
We never see commercials with men singing about ED, or old people singing about having dementia, but we’re subjected to fat people singing about T2D. Thanks so much, Big Pharma.

You can replace using butter or the fake stuff, margarine, with olive oil and won’t notice any significant difference.
I put it on baked potatoes, cook eggs in it and use it to ‘flavor’ vegetables, same as I would butter. Haven’t used the fake junk in decades.
Just be sure to keep the olive oil in a TIGHTLY SEALED CONTAINER IN THE DARK AWAY FROM LIGHT, else it will spoil from oxidation and be ‘rancid’...............
“Findings from a new mouse study indicate...Obese diabetic mice treated with elenolic acid showed improved blood sugar regulation and weight loss comparable to, or better than, current diabetic medications.”
Mice are herbivores (primarily). And it is already possible to regulate blood sugar and create weight loss by simple diet changes. The problem is too many doctors push the wrong changes, and too many people would rather die of diabetes than change how they eat.
If it leads to something, great, but it certainly doesn’t show humans would be helped by eating more olive oil.

I like olive oil and I love butter but I can definitely tell the difference. I would not put olive oil on waffles or hot biscuits nor would I make caprese balsamic reduction with butter.
I agree with you partially about storing olive oil. Cool and dark. But Olive oil will still go bad after many months. Just give it the sniff test. Bad olive oil takes on a waxy chemical smell in my experience
I’ve lost 10 pounds in the last six weeks by cutting out BREAD, SUGAR and most CARBS. No wheat products at all. Eating more protein will drop the weight fairly quickly. I also walk 3 miles most days......................
My A1C was just into diabetic territory and we decided to fix it with some lifestyle changes.
I eat out a lot due to extensive business travel. More fish. Especially salmon.
I drink zero sugar pop.
I also mix some Field of Greens from Brickhouse Nutrition and drink a glass of that every day.
That minor combination resulted in about 30 lbs weight loss and a huge drop in A1C. (7.5 to 6.2)
For the record, I hate olives so that won’t become part of my diet.
I understand the logic behind the sentence...but...as many doctors will tell you, diabetes never killed anyone. It's the associated issues brought on by diabetes that are the killers...neuropathy, high blood pressure, heart attacks, etc.
